After meeting Haitian President Rene Preval, Okada told a press conference that Japan will think of "additional measures" for the country on top of the $70 million it has already extended to Haiti for reconstruction and other purposes.

Okada also revealed a plan to dispatch a team of disaster-prevention experts to Haiti to offer Japan's know-how as an earthquake-prone country.

He added that Japan's support "will use taxpayers' money, so it must be used in ways that can gain the understanding of Japanese people."

The Japanese foreign minister also inspected the activities of Japan's Self-Defense Forces, which are involved in the U.N. peacekeeping operations in the country.

"The United Nations has said Japan's contributions serve as an example to other countries," Okada told the SDF troops. "That is primarily the result of the activities each one of you is carrying out under severe conditions."

Okada also met with Edmond Mulet, the acting head of the U.N. Stabilization Mission in Haiti, known as MINUSTAH, and told him he plans to attend an international donors' conference for Haiti to be held in New York at the end of March.
